Description

Technical Field

[0001] This invention relates to the field of animal behavior testing technology, and more specifically, to a primate behavior testing device suitable for microwave exposure environments. Background Technology

[0002] Microwaves are electromagnetic waves with frequencies ranging from 300MHz to 300GHz and wavelengths from 1mm to 1m. They are widely used in industries such as industry, communications, medicine, and the military. With the widespread application of microwave technology, people have begun to pay attention to and worry about the health effects of microwave radiation.

[0003] Working memory is a limited-capacity memory system that temporarily processes and stores information. It forms the basis for higher-level mental activities such as learning, thinking, and problem-solving, and is considered central to human cognitive activity. It is also a current focus of attention in cognitive psychology and cognitive neuroscience. Studies have shown that microwave exposure under certain conditions can affect the central nervous system, leading to impairments in cognitive functions such as learning and memory.

[0004] Animal behavior tests in microwave exposure environments often use rodents to study the impact of microwave exposure on working memory. However, rodents differ significantly from humans, limiting the relevance of their findings. Non-human primates such as macaques, as animal models more closely related to humans, offer more convincing results compared to rodent studies.

[0005] The primate behavior testing devices in the relevant technologies are not designed to take into account the application scenarios of microwave exposure environments, and therefore cannot be used in microwave exposure environments, especially not for real-time detection of animal behavior in microwave exposure environments. Summary of the Invention

[0006] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a primate behavior testing device suitable for microwave exposure environments, which also has advantages such as being suitable for electromagnetic exposure environments.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] The following description, with reference to the accompanying drawings, describes a primate behavior testing device 1 suitable for microwave exposure environments according to an embodiment of the present invention.

[0031] like Figures 1-5 As shown, the primate behavior testing device 1 suitable for microwave exposure environments according to an embodiment of the present invention includes a control terminal 10, an operation terminal 20, multiple light-transmitting buttons 30, multiple colored light sources 40, multiple pressure detection devices 50, a feeding trough 60, a pneumatic food dispensing device 70, and a fixed chair 80.

[0032] Multiple light-transmitting buttons 30 are mounted on the operating terminal 20. Multiple colored light sources 40 are mounted inside the control terminal 10 and are connected to the multiple light-transmitting buttons 30 via multiple transmission optical fibers 41. A press detection device 50 is used to detect whether the light-transmitting buttons 30 are pressed; multiple press detection devices 50 are located inside the control terminal 10 and are connected to the multiple light-transmitting buttons 30 via multiple detection optical fibers. A feeding trough 60 is mounted on the operating terminal 20. A pneumatic food dispensing device 70 is located inside the operating terminal 20 and is adapted to dispense food pellets 4 into the feeding trough 60. A fixed chair 80 is used to fix the primate 3. The operating terminal 20, feeding trough 60, pneumatic food dispensing device 70, and fixed chair 80 are all made of non-metallic materials.

[0033] Specifically, the colored light source 40 transmits light of different colors to the light-transmitting button 30 through the transmission optical fiber 41, so that the light-transmitting button 30 emits light of different colors, which is convenient for primates 3 to observe.

[0034] The pressed state of the light-transmitting button 30 is transmitted to the press detection device 50 through the detection optical fiber, thereby using the press detection device 50 to determine the pressed state of each light-transmitting button 30.

[0035] The pneumatic food dispensing device 70 dispenses food pellets 4 into the feeding trough 60 via gas drive. The pneumatic food dispensing device 70 is connected to a pneumatic pipeline to control the timing of dispensing, in order to reward specific behaviors of the primates 3.

[0036] The operating terminal 20, along with its light-transmitting button 30, feeding trough 60, pneumatic food dispensing device 70, and fixed chair 80 for securing the primate 3, constitutes the operating terminal equipment. The control terminal 10, along with its internal colored light source 40 and pressure detection device 50, constitutes the control terminal equipment. Since the operating terminal 20, feeding trough 60, pneumatic food dispensing device 70, and fixed chair 80 are all made of non-metallic materials, they will not affect the electromagnetic environment. The operating terminal equipment can be placed in the electromagnetic exposure environment 2, while the control terminal equipment can be placed outside the electromagnetic exposure environment 2. The operating terminal equipment and the control terminal equipment are connected only through optical fiber and pneumatic tubing, avoiding the influence of circuit connections on the electromagnetic exposure environment. This allows the primate behavior testing device 1, suitable for microwave exposure environments, to be used for primate behavior testing in electromagnetic exposure environments.

[0037] Furthermore, the primate behavior testing device 1, suitable for microwave exposure environments, can be used to evaluate the working memory of primates 3, and is designed based on the working memory paradigm—the Delayed Matching Task (DMTS) principle. The basic logic of the DMTS task process is to retain the memory of previously presented sample stimuli during the delay period, and then make the correct matching selection for different probe stimuli. The working memory performance is measured by accuracy and reaction time.

[0038] Before the formal behavioral test, primate 3 needs to undergo behavioral training. First, primate 3 needs to be accustomed to the primate behavior testing device 1 and know that it can obtain food rewards from the primate behavior testing device 1. Then, it needs to be taught that it can only obtain food after responding to light stimuli. Finally, it needs to learn the rules of the DMTS task.

[0039] During the formal behavioral test, after the task program is set on the control device, the primate 3 is fixed in front of the operating terminal 20 using a fixed chair 80, with the primate 3 facing the light-transmitting button 30. The colored light source 40 of the control device presents visual stimulation to the primate 3 through the transmission optical fiber 41 and the light-transmitting button 30. Under the visual stimulation, the primate 3 performs a pressing operation. The pressing detection device 50 judges whether the primate 3 has performed the correct pressing operation by judging the pressing status of the light-transmitting button 30 transmitted by the detection optical fiber. After receiving the signal, the control device controls the pneumatic food dispensing device 70 to dispense the corresponding food reward based on the primate 3's behavioral task performance.

[0040] According to an embodiment of the present invention, the primate behavior testing device 1 suitable for microwave exposure environments, by using non-metallic materials for the operating terminal 20, feeding trough 60, pneumatic food dispensing device 70, and fixed chair 80, will not affect the electromagnetic environment. The operating terminal equipment can be placed in the electromagnetic exposure environment 2, while the control terminal equipment is placed outside the electromagnetic exposure environment 2. Moreover, the operating terminal equipment and the control terminal equipment are connected only through optical fiber and pneumatic pipeline, avoiding the influence of circuit connection on the electromagnetic exposure environment and avoiding electromagnetic interference caused by circuit connection. This allows the primate behavior testing device 1 suitable for microwave exposure environments to be used for primate behavior testing in electromagnetic exposure environments, and gives the primate behavior testing device 1 suitable for microwave exposure environments good electromagnetic compatibility. It can be used not only in real-time microwave environments but also in electromagnetic radiation of various frequency bands, improving the applicability of the primate behavior testing device 1 suitable for microwave exposure environments.

[0041] Therefore, the primate behavior testing device 1 suitable for microwave exposure environments according to the embodiments of the present invention has the advantages of strong applicability.

[0042] The following description, with reference to the accompanying drawings, describes a primate behavior testing device 1 suitable for microwave-exposed environments according to a specific embodiment of the present invention.

[0043] In some specific embodiments of the present invention, such as Figures 1-5 As shown, the primate behavior testing device 1 suitable for microwave exposure environments according to an embodiment of the present invention includes a control terminal 10, an operation terminal 20, multiple light-transmitting buttons 30, multiple colored light sources 40, multiple pressure detection devices 50, a feeding trough 60, a pneumatic food dispensing device 70, and a fixed chair 80.

[0044] Specifically, such as Figure 4 As shown, the translucent button 30 includes a button housing 31, a button body 32, and a resilient element 33. The button housing 31 is located within the operating terminal 20. The button body 32 is movably mounted on the button housing 31 and protrudes from the operating terminal 20 between a pressed position and a released position. The resilient element 33 is located within the button housing 31 and normally drives the button body 32 to move towards the released position. Both the button housing 31 and the button body 32 are made of non-metallic materials. This design allows the translucent button 30 to be pressed normally and reset using the resilient element 33, and also provides good electromagnetic compatibility for the translucent button 30.

[0045] Those skilled in the art will understand that since the elastic element 33 is far from the head and body of the primate 3, it has little impact on the microwave exposure of the primate 3, and therefore can be made of metal or partially of metal.

[0046] Furthermore, the elastic element 33 includes a spring and a microwave-absorbing material layer wrapped around the spring. Preferably, the thickness of the microwave-absorbing material layer is greater than or equal to 5 mm. This can further reduce the impact of the elastic element 33 on the microwave exposure environment.

[0047] Advantageously, the button body 32 is made of nylon. This gives the button body 32 good self-lubricating properties, allowing it to slide smoothly, preventing it from jamming, and ensuring that it can be pressed and reset smoothly.

[0048] Specifically, the operating terminal 20 is made of PVC (polyvinyl chloride) material.

[0049] There can be 5 light-transmitting buttons (30).

[0050] More specifically, such as Figure 4As shown, the detection optical fiber includes a transmitting optical fiber 51 and a receiving optical fiber 52. Each press detection device 50 is connected to a light-transmitting button 30 through the transmitting optical fiber 51 and the receiving optical fiber 52. One end of the transmitting optical fiber 51 is connected to the press detection device 50 and has a transmitting end 511 away from the press detection device 50. One end of the receiving optical fiber 52 is connected to the press detection device 50 and has a receiving end 521 away from the press detection device 50. The transmitting end 511 and the receiving end 521 extend into the button box 31 and are arranged opposite to each other inside the button box 31. A light-shielding plate 321 is provided on the button body 32. When the button body 32 is in the pressed position, the light-shielding plate 321 blocks the transmitting end 511 and the receiving end 521. When the button body 32 is in the lifted position, the light-shielding plate 321 avoids the imaginary connection between the transmitting end 511 and the receiving end 521. When the light-transmitting button 30 is pressed, the button body 32 is in the pressed position, and the light-shielding plate 321 blocks the light between the transmitting end 511 and the receiving end 521, so that the light emitted by the transmitting end 511 is blocked by the light-shielding plate 321 and cannot be received by the receiving end 521. When the light-transmitting button 30 is lifted, the button body 32 is in the lifted position, and the light-shielding plate 321 avoids the imaginary connection between the transmitting end 511 and the receiving end 521, so that the light emitted by the transmitting end 511 can be received by the receiving end 521. Thus, the pressing detection device 50 can determine the pressing state of the corresponding light-transmitting button 30 by the light receiving state of the receiving end 521. Moreover, it avoids setting up an electronic control structure at the operating end device, further ensuring the electromagnetic compatibility of the primate behavior testing device 1 suitable for microwave exposure environments.

[0051] Specifically, the press detection device 50 can be a light sensor. The transmission optical fiber 41 can be thicker than the detection optical fiber to ensure reliable light emission from the light-transmitting button 30 and to improve the brightness adjustment range of the light-transmitting button 30. The colored light source 40 can emit light of at least seven different colors, including red, yellow, blue, green, cyan, white, and purple.

[0052] Figure 3 and Figure 5 A primate behavior testing device 1 suitable for microwave exposure environments is shown, according to some examples of the present invention. For example... Figure 3 and Figure 5As shown, the pneumatic food dispensing device 70 includes a dispensing box 71, an upper conveying pipe 72, a lower conveying pipe 73, a slider 74, a first pneumatic pipeline 75, and a second pneumatic pipeline 76 (the vertical direction is shown by the arrows in the figure and is only for ease of description, not a limitation on the actual setting direction). The dispensing box 71 has an upper outlet on its upper surface and a lower outlet on its lower surface, and the upper and lower outlets are offset in the vertical direction. One end of the upper conveying pipe 72 is connected to the upper outlet and the other end is connected to the air source 77. A food pellet dispensing port 721 is provided between the two ends of the upper conveying pipe 72, and the upper conveying pipe 72 has a spiral coil section 722 for storing food pellets 4. One end of the lower conveying pipe 73 is connected to the lower outlet and the other end is connected to the food trough 60. The slider 74 is provided with a pellet inlet 741. The slider 74 is slidably disposed in the dispensing box 71 between a first position and a second position. When the slider 74 is in the first position, the pellet inlet 741 is opposite to the upper inlet in the vertical direction. When the slider 74 is in the second position, the pellet inlet 741 is opposite to the lower inlet in the vertical direction. The dispensing box 71 is also provided with a first pneumatic inlet and a second pneumatic inlet. The first pneumatic inlet and the second pneumatic inlet are respectively located on opposite side walls of the dispensing box 71. One end of the first pneumatic pipe 75 is connected to the first pneumatic inlet and the other end is connected to an air source. One end of the second pneumatic pipe 76 is connected to the second pneumatic inlet and the other end is connected to an air source. The first pneumatic pipe 75 and the second pneumatic pipe 76 are configured to be adapted to blow the slider 74 to the first position through the first pneumatic pipe 75 and to blow the slider 74 to the second position through the second pneumatic pipe 76. Specifically, firstly, pellets 4 are added to the upper conveying pipe 72 through the pellet inlet 721. Gas is supplied to the upper conveying pipe 72 using the air source 77 to drive the pellets 4 in the upper conveying pipe 72 to move into the feeding box 71. Since a spiral coil section 722 is provided, the spiral coil section 722 can be used to store the pellets 4, increasing the number of pellets 4 that can be stored in the upper conveying pipe 72 and reducing the frequency of adding pellets 4 to the upper conveying pipe 72. Then, gas is supplied to the first pneumatic pipeline 75 using the air source 77 to drive the slider 74 to move to the first position, so that the pellets in the upper conveying pipe 72 can fall into the pellet outlet 741. Finally, gas is supplied to the second pneumatic pipeline 76 using the air source 77 to drive the slider 74 to move to the second position, so that the pellets 4 in the pellet outlet 741 can fall into the lower conveying pipe 73, thereby feeding the pellets 4 into the feeding trough 60 through the lower conveying pipe 73. Therefore, the pneumatic drive of the pellet 4 can be realized through the upper conveying pipe 72, and the timing of the pellet 4 can be controlled by the first pneumatic pipe 75 and the second pneumatic pipe 76, thereby achieving reliable pellet delivery.

[0053] Furthermore, the upper delivery pipe 72 and the lower delivery pipe 73 can both be made of plastic tubing, unlike the first pneumatic pipeline 75 and the second pneumatic pipeline 76. The upper delivery pipe 72 and the lower delivery pipe 73 can also be thicker than the first pneumatic pipeline 75 and the second pneumatic pipeline 76. The air source 77 can be an air pump, and the upper delivery pipe 72, the first pneumatic pipeline 75, and the second pneumatic pipeline 76 are connected to the air pump via an electromagnetic switching valve. Thus, the air pump's gas delivery pipeline can be controlled via the electromagnetic switching valve, thereby achieving pneumatic control of the pneumatic food dispensing device 70. The upper delivery pipe 72, the first pneumatic pipeline 75, and the second pneumatic pipeline 76 can also be connected to a pressure regulating valve to ensure the stability of airflow and food pellet movement, as well as a regulating valve to adjust the airflow magnitude.

[0054] The slider 74 can be made of polyoxymethylene (POM). This gives the slider 74 good self-lubricating properties, making its sliding smoother.

[0055] Advantageously, the primate behavior testing device 1, which is suitable for microwave exposure environments, also includes a detection delivery device, a detection transmitting optical fiber, and a detection receiving optical fiber.

[0056] The delivery detection device is located within the control terminal 10. One end of the delivery detection transmitting optical fiber is connected to the delivery detection device and has a delivery detection transmitting end. One end of the delivery detection receiving optical fiber is connected to the delivery detection device and has a delivery detection receiving end. Both the delivery detection transmitting end and the delivery detection receiving end are connected to the lower delivery pipe 73 and are arranged opposite to each other. In this way, when the pellet 4 passes through the lower delivery pipe 73, it will block the delivery detection transmitting end and the delivery detection receiving end, so that the light emitted by the delivery detection transmitting end cannot be received by the delivery detection receiving end. Therefore, the reception status of the delivery detection receiving end can be used to determine whether the pellet 4 has passed through the lower delivery pipe 73 and whether the pellet 4 has been reliably delivered.

[0057] Figure 2 A primate behavior testing device 1 suitable for microwave exposure environments is shown, according to some examples of the present invention. For example... Figure 2 As shown, the primate behavior testing device 1 suitable for microwave exposure environments also includes a height-adjustable lifting base 90, on which the operating terminal 20 is mounted. The lifting base 90 is equipped with a handle 91. This allows for easy adjustment of the height of the operating terminal 20 via the lifting base 90 to accommodate primates 3 of different heights, further improving the applicability of the primate behavior testing device 1 suitable for microwave exposure environments. Furthermore, the handle 91 facilitates the transportation of the primate behavior testing device 1 suitable for microwave exposure environments.

[0058] Optionally, the height adjustment range of the lifting base 90 is 10cm-30cm.

[0059] Advantageously, such as Figure 2 As shown, the primate behavior testing device 1 suitable for microwave exposure environments also includes a connecting arm 81. The two ends of the connecting arm 81 are connected to the operating terminal 20 and the fixed chair 80, respectively, and the axis of rotation is oriented horizontally. This not only allows the fixed chair 80 to be positioned using the connecting arm 81, preventing it from shifting or tipping over, but also facilitates height adjustment of the operating terminal 20 through the rotation of the connecting arm 81.

[0060] More advantageously, the feeding trough 60 is equipped with a cushioning pad for buffering the food pellets. Specifically, the feeding trough 60 can be bowl-shaped, and the cushioning pad can be a flexible pad to reduce the probability of the food pellets 4 falling out of the feeding trough 60 after collision.

[0061] Specifically, the assembly of the operating terminal 20 and the connection of its various structures can be made using polyamide (PA) screws.

[0062] Figure 1 A primate behavior testing device 1 suitable for microwave exposure environments is shown, according to some examples of the present invention. For example... Figure 1 As shown, the primate behavior testing device 1 suitable for microwave exposure environments also includes a display and control panel 11, which is located on the control terminal 10. This allows the display and control panel 11 to control the primate behavior testing device 1 suitable for microwave exposure environments and to display test results for easy observation by the operator.

[0063] Specifically, primate 3 can be a rhesus monkey.

[0064] The display and control panel 11 can have a built-in control program for setting up behavioral task programs, receiving the detection results from the pressing detection device 50, controlling different colored lights that provide visual stimulation in the behavioral task, and controlling the pneumatic force of the food pellet reward, so as to realize the connection between the various modules of the primate behavior testing device 1 suitable for microwave exposure environment.

[0065] The display and control panel 11 can adopt an embedded microcontroller system with a human-computer interaction interface. It allows users to set software programs that perform different tasks and record experimental data. The main interface of the human-computer interaction interface can display the illumination status of five buttons and the progress of the experimental task. The experimental process can be controlled through the "Start," "End," and "Pause" options.

[0066] The human-computer interface also allows access to the program settings interface via the "Settings" option, which includes three task programs: feeding learning, pressure learning, and DMTS task.

[0067] Feeding learning can be programmed with fixed or random intervals for automatic food pellet dispensing, fostering familiarity with the device in macaques and motivating them to learn how to obtain food from it. Press learning, based on the principles of operant conditioning, aims to teach macaques to press illuminated buttons to receive a food pellet reward. The DMTS task can be used to teach macaques the principles of the DMTS task and to conduct behavioral tests. According to the DMTS task principle, one of the five illuminated buttons (e.g., the central illuminated button) is preset as the sample light button. The task steps are as follows: first, the sample light button displays a color; after the macaque presses it, there is a delay period during which it needs to memorize the color. After the delay period, the remaining four buttons display different colors, one of which matches the sample light button color. If the macaque presses the sample light button, it receives a food reward; otherwise, no reward is given. In the basic settings, parameters such as the light stimulus presentation time and the delay period length can be adjusted. In press learning and the DMTS task, each button can be configured individually. You can choose the number of buttons to use. Clicking a button icon will take you to the button's color settings interface, where you can flexibly adjust the difficulty of the task by choosing whether to use the button and its color. In the prompt sound settings interface, you can select whether to provide prompts for each step of the task.

[0068] The main interface of the human-computer interaction interface allows users to view data through the "Data" option. The control terminal 10 is equipped with a USB data export interface for inserting an external USB flash drive. Experimental data can be directly recorded into the USB flash drive, including information on each step of the behavioral task, such as reaction time, correctness, and color, for further detailed analysis.
